'Occupation' in the Bible

And it shall come to pass that when Pharaoh shall call you and say, What is your occupation?

And Pharaoh said to his brethren, What is your occupation? And they said to Pharaoh, Thy servants are shepherds, both we and our fathers.

And I applied my heart to seek and search out by wisdom concerning all that is done under the heavens: this grievous occupation hath God given to the children of men to weary themselves therewith.

There is one alone and without a second; also he hath neither son nor brother: yet is there no end of all his labour, neither is his eye satisfied with riches, and he saith not, For whom then am I labouring, and depriving my soul of good? This also is vanity and a grievous occupation.

And they said unto him, Tell us, we pray thee, for whose cause this evil is upon us: what is thine occupation? and whence comest thou? what is thy country? and of what people art thou?
